We ordinary people can't understand the profound theory, and there is no need to understand it too much. What we need to know may be some very practical knowledge. For example, the following problems related to penis erection:
1. At what age do people have erections, and when will erections become abnormal
Generally speaking, people's first physical erection occurs when they are 5-6 years old or younger in childhood, and this situation has nothing to do with sexual experience. Later, erections will become more frequent, and the occurrence of erections will become a manifestation of sexual desire to the opposite sex in the mature stage of sexual development. Men have the strongest erectile ability around the age of 20. Later, the erectile ability gradually decreases, and the time of erectile disappearance varies from person to person. Some people can maintain it until the age of 90, while some people will lose their "strength" when they reach the age of 40.
2. What disease can lead to the loss of catching ability
The first is alcoholism, because large doses of alcohol have fatal damage to men's penis erection ability. At the same time, drugs, especially narcotic drugs such as cocaine and amphetamine, can enhance sexual ability in a short time, but after a few applications, they can "eliminate" the erectile ability of people. Diabetes, some endocrine diseases, prostatitis and arteriosclerosis, especially those of reproductive organs, also reduce erectile capacity. In addition, if the male hormone is abused without the guidance of a doctor, the level of male hormone in the body is too high, which can also damage the male erectile function. Obviously, long-term depression, psychological stress and anxiety can also weaken the ability to erect.
